Squeaky home button and freezing OS

[makajtije]

Hello, I just bought this phone yesterday, so there is not a lot of stuff installed on it but those are the problems that I'm experiencing:

1. My home button is somewhat squeaky when I click it, sometimes It's fine but most of the time it makes really ugly noise.

2. When I'm on my phone and just scrolling up/down and I get a message my phone would just freeze with long vibration and no notification sound coming from it. I can reproduce this error anytime.

What shall I do, phone is one day old?
I did reboot and close all running apps.
